Best way to handle configuration in JSON - merging two variants

hnb · 2015-10-13 08:18:18

Hi,

what is most proper way to merge two TDocVariantData variants into one?
First variant "A" is with default configuration, second variant "B" contains values loaded from *.json file (and some values can be omitted).

To perform right behavior I need to fill missing values inside "B" (by using "A"). How to do something like this? :

B.AddOrUpdateIfValueIsNull(A);

I've introduced the TDocVariantData.AddOrUpdateObject method, with an optional OnlyAddMissing parameter.
With OnlyAddMissing=true, you should have what you need.
